Flanked by Sen. Ted Cruz, Republican U.S. Senate candidate Darryl Glenn made what he called his closing argument Wednesday, saying Democratic rival Michael Bennet’s support for the Iran deal and federal health care law disqualify him for office.

“When he’s telling you that’s he’s bipartisan and he’s upset about how the system is broken, he is part of the problem,” Glenn told a crowd of 75 at the Park Hill Country Club in Denver.

Cruz made two stops in Colorado to rally support for Glenn — the first candidate he endorsed after leaving the presidential race — and labeled Bennet a “rubber stamp” for Democrat Hillary Clinton.

“Not only do we need to pick up this seat to hold the Republican Senate majority,” Cruz said, “we desperately, desperately, desperately need more Republicans in the Senate with backbone.”

The Texas senator didn’t mention Republican Donald Trump but emphasized the need for a check on a potential Democratic win in November.

“If God forbid, Hillary wins this thing, and I pray that she does not, but if that happens, we desperately need a Republican Senate to check the president,” Cruz said, as a member in the crowd shouted that lawmakers should “impeach her.”

“And let me tell you, even if the Republican nominee wins the presidency,” Cruz continued, “we still need a Republican Senate to check the president because that’s the constitutional responsibility of the Senate whether the president is Democrat or Republican.”

Earlier in the day, at a stop with Glenn in Loveland, Cruz suggested the Senate could continue to block Supreme Court nominee Merrick Garland indefinitely, according to media reports.

A Bennet spokesman suggested Glenn would only exacerbate the polarization in the nation’s capital.

“By calling Democrats ‘evil,’ saying he knows zero elected Democrats he gets along with and repeatedly stating that the problem with Washington is ‘Republicans reaching across the aisle,’ Glenn has made clear that as a senator he would only add to Washington’s dysfunction,” said Andrew Zucker, referring to the GOP candidate’s statements on the campaign trail.

Sticking to his core issues, Glenn said a requirement to balance the federal budget is needed to boost the economy and called for congressional term limits — two for senators and three for House members. Glenn also agrees with Cruz’s pledge to implement a flat tax and abolish the IRS.

U.S. Sen. Michael Bennet is taking the final steps toward becoming the second Colorado Democrat in the 2020 race for president, with an announcement possibly coming as soon as next week, sources familiar with his plan have told The Denver Post.

Voters are undecided about a new state law that ties Colorado’s Electoral College votes to the presidential candidate who wins the popular vote across the nation, according to a new poll released Thursday.
